We divide 67920416 by 138
Our goal is to divide 67920416 by 138.

Step 1:
When dividing 6 by 138, we get 0 with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Fetch the next digit (7) from the dividend, attach it to 6 and continue: 67 / 138

Step 2:
If we divide 67 by 138, we get 0 and a remainder of 67.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 67 after subtracting 0 from 67.
Fetch the next digit (9) from the dividend, attach it to 67 and continue: 679 / 138

Advancing to step 3:
679 divided by 138 is 4 with a remainder of 127.
Write down 4 as next digit of the result. 
Result so far: 4.0
Subtracting 552 from 679 leaves us with 127.
Include the next digit (2) from the dividend after 127, then repeat: 1272 / 138

Going ahead to step 4:
When dividing 1272 by 138, we get 9 with a remainder of 30.
Record the quotient 9 as the next digit in the result. 
Result so far: 49.0
Subtracting 1242 from 1272 leaves us with 30.
Include the next digit (0) from the dividend after 30, then repeat: 300 / 138

Moving on to step 5:
138 goes into 300 2 times with a remainder of 24.
Record the quotient 2 as the next digit in the result. 
Result so far: 492.0
The remainder is 24 after subtracting 276 from 300.
Include the next digit (4) from the dividend after 24, then repeat: 244 / 138

Let's proceed to step 6:
When dividing 244 by 138, we get 1 with a remainder of 106.
The number 1 becomes the next digit in our result. 
Result so far: 4921.0
Deduct 138 from 244 and we're left with 106.
Grab the next digit (1) from the dividend, add it to 106, then carry on: 1061 / 138

On to step 7:
138 can be fit into 1061 7 times, resulting in a remainder of 95.
The number 7 becomes the next digit in our result. 
Result so far: 49217.0
Subtracting 966 from 1061 leaves us with 95.
Append the next digit (6) from the dividend to 95 and continue with: 956 / 138

Step 8:
956 divided by 138 is 6 with a remainder of 128.
Put 6 as the next digit of the answer. 
Result so far: 492176.0
Subtracting 828 from 956 leaves us with 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

On to step 9:
138 can be fit into 1280 9 times, resulting in a remainder of 38.
The next digit of our result is 9. 
Result so far: 492176.9
The remainder is 38 after subtracting 1242 from 1280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Step 10:
If we divide 380 by 138, we get 2 and a remainder of 104.
Put 2 as the next digit of the answer. 
Result so far: 492176.92
If we subtract 276 from 380, we get 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

On to step 11:
1040 divided by 138 is 7 with a remainder of 74.
Record the quotient 7 as the next digit in the result. 
Result so far: 492176.927
If we take 966 away from 1040, we end up with 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Going ahead to step 12:
740 divided by 138 is 5 with a remainder of 50.
Use 5 as the next digit of our solution. 
Result so far: 492176.9275
Subtracting 690 from 740 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

On to step 13:
500 divided by 138 is 3 with a remainder of 86.
Record the quotient 3 as the next digit in the result. 
Result so far: 492176.92753
If we take 414 away from 500, we end up with 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

Step 14:
If we divide 860 by 138, we get 6 and a remainder of 32.
Record the quotient 6 as the next digit in the result. 
Result so far: 492176.927536
If we take 828 away from 860, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Going ahead to step 15:
138 goes into 320 2 times with a remainder of 44.
Put 2 as the next digit of the answer. 
Result so far: 492176.9275362
Subtract 276 from 320 to get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

On to step 16:
138 goes into 440 3 times with a remainder of 26.
The number 3 becomes the next digit in our result. 
Result so far: 492176.92753623
Subtracting 414 from 440 leaves us with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

The final outcome is 492176.92753623, with a leftover of 2.6e-08.
